Hi everybody !
I am super excited to use this beautiful tool Launch-Dashboard-API. Personally, I am using only Python script (I know pretty close to 0 in js) so I was wondering if it was possible to do it with request. I have already exchanged data with APIs like the Google Maps API so I know how request work but currently I am having some problems with this API for a few tests.
import requests
url = "https://api.launchdashboard.space/v2/launches/spacex?flight_number=45"
payload={}
headers = {}
response = requests.request("GET", url, headers=headers, data=payload)
print(response.text)
Then I get the following error.

Sorry it is in french as my jupyter notebook. I was wondering if the server is down or I am doing it all wrong @shahar603 ?
Thx in advance for the help 😀

I have tried the nodeJS example here: https://github.com/shahar603/Launch-Dashboard-API/wiki/Live-(Websockets)
And also tried simple websocket client google chrome extensions connecting to both
ws://api.launchdashboard.space and wss://api.launchdashboard.space
All attempts to connect give an error that the server has disconnected the connection.
I was trying to connect to the WebSocket server (wss://api.launchdashboard.space/), but looks like there is some problem. I ran the sample code in Node.js with success, but it's the only one which works - I tried a few libraries in C#, online WebSocket clients and they can't connect.
You can check it here for example: http://demos.kaazing.com/echo/index.html. When trying to connect, the log shows these messages:
CONNECT: wss://api.launchdashboard.space/
CLOSED: (1006)
Looking at the developer console in Chrome we get some additional info:
WebSocket connection to 'wss://api.launchdashboard.space/?.kl=Y' failed: Connection closed before receiving a handshake response
I don't know Node.js too well to check code in your backend, but I've searched in Google and looks like it's quite common problem with Socket.io library, especially when someone creates by accident two instances of it on example. Sample links:
GitHub issues -
socketio/socket.io#2045
feathersjs-ecosystem/socketio#84
StackOverflow -
https://stackoverflow.com/questions/26665840/socket-io-failed-connection-closed-before-receiving-a-handshake-response/44196108
I have tried to connect to the websocket, but the server simply disconnects me. Furthermore, I can't seem to find any recent launch telemetry.
Are you still running the videostream/scraper software?
If you have suggesions, requests for data you want the API to contain (for example telemetry from a launch provider which isn't covered by the API), this is the place to post them.
There is a small mismatch between what the documentation says, and what API returns from the endpoints: "analysed", "events", "raw". We can read that all of them have mission header (with fields: "mission_id", "name", "flight_number", "launch_libray_id") like this:
{
"mission_id": "amos-17",
"name": "Amos-17",
"flight_number": 83,
"launch_library_id": 1388,
"events": [
{ "key": "maxq", "time": 66 },
{ "key": "throttle_down_start", "time": 45 }
]
}
But looks like API returns data without header, and contains only array with requested data:
[
{ "key":"maxq", "time":66 },
{ "key":"throttle_down_start", "time":45 }
]
The only endpoint which contains mission header is "launches", and here documentation is correct.
Hi Shahar. The server at api.launchdashboard.space has been down for the last few days. I was hoping to take a look at some more recent launch data.
Dear Sharhar603,
I have been looking closely at your live telemetry feed and the Telemetry API/WebSockets and I am very interested in trying this capability into our core software at Saber Astronautics.
Is there a good email address I can get in touch with you at? Alternatively, feel free to send me an email to: [email protected]
